Dual Public Events on Saturday 8th April!

1. Public Lecture

5.30 pm sharp at WSU

Campbelltown Rotary Observatory has invited Don Whiteman (Binocular & Telescope Shop) to give a talk on Telescopes on Saturday 8 April 2017, from 5.30pm to 6.30pm in Lecture Theatre 3, Building 21, Western Sydney University. Don is one of Australia's foremost experts on optical equipment for amateur and professional astronomy purposes.

This lecture will be ideal if you are considering purchasing a telescope or if you are simply interested in brushing up on how they work. 

Public parking for the lecture is available in the large car parks P6 or P11 (see map of University) but you must not park in the residential Car Parks P10 or P12. 

After the lecture it will take a few minutes to walk up to the Observatory Building 29.

2. Public Observing Night

From 6.30 pm at Campbelltown Rotary Observatory

In collaboration with the Campbelltown Rotary Observatory and Dr Ragbir Bhathal (Western Sydney University), MAS will be conducting a public observing night at the Observatory in Macarthur Heights on Saturday 8th April (from 6.30 pm). We hope that you enjoy a very pleasant evening with us as we show you our Universe!

Weather: the event is weather permitting. Closer to the date we will post a weather outlook right here. If conditions are in doubt due to inclement weather, please check this page for announcements before leaving home. The event is predominantly outdoors, so please bring warm clothing.

Location: the twin-domed Campbelltown Rotary Observatory is located near the corner of University Drive and Milky Way, Macarthur Heights. For a detailed map, please visit our "On The Map" page from the top menu above.

Public Admission: there is no need to book and there will be no entry charge. However, if you enjoy the evening, MAS will gratefully accept a gold coin in our black donation box.

Children: families with children are welcome to attend. We simply request that you keep your children with you at all times and instruct them not to touch the telescopes.

Safety: the pursuit of astronomy requires a dark environment and attendance is at your own risk. We can accept no responsibility for accidents that occur. 

Lighting: There will be some moonlight on this particular evening. Limited red safety lighting is provided near the observatory. If you choose to bring a torch, please avoid glare when near the telescopes by covering it with red cellophane. We request that you do not use flash photography. Thanks.

Telescopes: both of the Observatory Domes will be open, with their 16” and 12” diameter Meade LX-200 Schmidt-Cassegrain telescopes. In addition, MAS members will have a number of their own private telescopes set up for the public to view through.

What's Up: our multiple telescopes can show you numerous interesting night sky objects which are up on the night, including the Moon and Jupiter.

Dress: please ensure that you wear warm clothing. The observatory is exposed and the temperature is likely to be very cold.

No Facilities:  please note carefully that there are no toilet facilities at the Observatory. We regret this.

MAS Astro Observing

Members Private Observing Nights


Forest weekends are held close to New Moon. Stargard is held on the second best weekend each cycle and public nights are usually held near First Quarter Moon.

Members must arrange their own transport and bring their own food, drink and warm clothing. It is also essential - for your own safety and that of others - that you bring a red torch with you to observing nights. You should arrive before sunset. Location maps of our observing sites are accessed via the menu at the top of this page.

If arriving late, make sure that your approach to the final gate is with only parking lights and ask someone to guide you safely into the observing area.

If weather conditions look doubtful, please check this page AND the Facebook page AND your Private Messages before leaving home and please ensure you have saved the relevant contact numbers on your mobile phone.


Please consider the needs of others around you, especially when using laser pointers, camera and computer monitors, car boot and interior lights etc. Please read our Field Etiquette page from the menu at the top of this page.

Stargard Observing


Stargard nights at The Oaks (adjacent to The Oaks Airport) are free to financial members and invited guests only. Please contact the President before inviting non-members to attend.

Beginners are particularly encouraged to observe at Stargard before progressing to the Forest. Members who have not yet purchased a telescope and  wish to familiarise themselves with what other members use are welcome to attend and seek advice from more experienced members.

Stargard observing dates are scheduled for one Saturday of each Lunar cycle, either the week before The Forest or the week after.

If a scheduled night is cancelled due to weather, another night may be selected.


Members are requested to always close the main gate and throw the bolt without locking it, to discourage entry by non-authorised people but permit entry or egress by members.

The Forest Observing

The Forest Cabin Under the Stars, copyright Tony Law  

The cabin at Belanglo Forest is our premier dark-sky observing site, normally open on the Weekend closest to the New Moon. Bring your equipment and observe or photograph our Forest sky which really has to be seen to be believed on a clear night. Limited sleeping accommodation is available but depending on the numbers is not guaranteed.

Non-members who are experienced amateur astronomers may be invited to attend the Forest, subject to prior clearance from the President.

Use of the site between Sunday morning and Monday morning will be dependent on the number of members each month who express a desire to attend. Members who have paid for two nights will get the third night free. 

Forest Charge for members: $20 for one night, $35 for two nights, third night free (per member), whether attending just for the evening or staying all night. Please see Ned Pastor or Tony Law on your arrival to make your payment and please try to have the exact amount. 

Charge for invited non-members: $25.00 for one night and $45.00 for two nights, third night free.

Free weekend: each financial member is entitled to one free Forest weekend per year. Bring your current membership card with you when you come to a New Moon Weekend and it will be punched, signifying that you've taken your free weekend.
